Like a lot of people on here, I wasn't too impressed with the vice vibrator when applied to the prostate. That kind of stimulation seems to feel good for a short while, but quickly goes numb. Not subtle enough. But i've found a good use for the vibe. All you need is an ACE bandage cut down to about 2 feet.

Put the vibe with the base/button end resting on your frenulum (the area just under the bottom side of your cock head). Wrap the ACE bandage around your dick to bind the vibrator to it. The vibe is more intense near the button end, plus you'll have an easy time changing settings. Just turn it on and see what it feels like. Frenulum stimulation is pretty amazing and this is a great handsfree way to get it.
